Abstract
Embodiments of the disclosure provide a method and device for controlling lost circulation in a target lost circulation zone in a borehole. A swellable lost circulation material device includes a permeable membrane and a swellable lost circulation material enclosed within the membrane. The swellable lost circulation material device in a non-swollen state is introduced to a target lost circulation zone where a fluidic component permeates into the swellable lost circulation material device through the membrane such that the fluid component is in contact with the swellable lost circulation material such that the swellable lost circulation material device transitions to a swollen state.
